Webinput for feature extraction and 3D reconstruction algorithms. 2.2. OBJECTIVES The objective of this work is to give a brief introduction to SfM photogrammetry and develop a methodology initially used in capturing photographs through the fisheye lens and processing them for the creation of a 3D model from the section of the lower WebPreviously, action cameras were considered inappropriate for accurate 3D reconstructions due to radial distortion created by the wide angle of view (AOV) or fisheye lens. AOV is a function of sensor size and lens type and describes the angular extent of a camera's view. WebIn this report, we proposed a 3D reconstruction method for the full-view fisheye camera.
